Cloud Cost Transparency, Control, and Saving $3M on Amazon EKS: How Iterable Does It

“When you start talking about those numbers, leadership cares, finance cares, they start building it into their cost projections and estimates. Even 1 or 3% of a massive AWS bill is significant. So when you say numbers like 20% people are losing their minds. And our total possible savings take that 20% closer to 60 or 70%, which translates to $3-4 million per year.”
